Resumen

The transient heat and mass transfer in skin is investigated numerically using a finite difference method. Based on the skin physical structure, a three-dimensional multilayer model is developed and the governing equation is discretized using the Crank-Nicholson scheme. The resulting sparse linear system is solved by the generalized minimum residual method with an incomplete lower upper factorization with threshold (ILUT) preconditioner. The performance of the incomplete lower upper triangular factorization (ILUT) preconditioner is evaluated for different thresholds, solvers, and mesh sizes.
